Hi, Im having a bit of a problem with a Charger.
The system currently is being used a battery backup for controlling valves when the power fails.
I have 2 x E-Guard Battery NH12-100W 12V 28Ah hooked up to produce 24V.
Being charged by a Victron Blue Smart Charger 24V 16A. But now, only a week into the use both batteries have shown bulging. The installer now claims that the charger is too big for the batteries.
I would just like to confirm the correct battery configuration /recommended changes to be used/made to supply 12amps max load @ 24vdc for 5minutes without damaging the batteries when charging.
Thank you in advance for any help offered.
